What kind of people are suicide bombers?

Not necessarily. I mean it's going to sound racist, but I don't mean it to be. But it seems like most suicide bombers are radical Muslims. Now I'm not speaking against Muslims in general because the radical ones are such a tiny amount. But I mean I mean it's rare to see a suicide bomber that isn't connect to a radical islamic group. But I'm not saying they are the only people who commit terrorist actions. Looks at the unibomber, columbine or Virginia tech. All those people were terrorists, but they weren't suicide bombers.
